WebApr 24, 2024 · Definition. Suppose that Z has the standard normal distribution, V has the chi-squared distribution with n ∈ (0, ∞) degrees of freedom, and that Z and V are independent. Random variable T = Z √V / n has the student t distribution with n degrees of freedom. The student t distribution is well defined for any n > 0, but in practice, only ... WebX and X̅ are standardised slightly differently. In both cases, the denominator is the square root of the variance, like so: For X, Z = (X-μ) / σ. For X̅, Z = (X̅ - μ) / (σ / √n) This fits with what we know about the central limit theorem. For X, the variance is σ². WebApplications of Fisher’s z Transformation.

WebIn the case of the t distribution we have a N (0,σ 2) divided by V where V is the sample estimate of σ. V is proportional to a chi-square with n-1 degrees of freedom where n is the sample size. The degrees of freedom for the t is the degrees of freedom for the chi-square random variable that is involved in the calculation of V.
